Hello,
I'm trying to run simple program with gpio interrupt, but processor jumps to invalid address in reset vector.
I put breakpoints from 0x04 to 0x1c. When I push the button -> core immediately jumps to 0x08 instead to 0x18.
Because of breakepoints I can see vim registers and they look fine to me except one:
IrqVecReg contains 0x541 and that is my phantomInterrupt_handler address. Despite the fact that 23th word from address 0xFFF820000 (ISR) contains 0xb69 and that is correct gpioInterrupt_Handler.
Why core jumps to SoftwareInterrupt?
I'm including list of vim registers and screenshoot of paused program and memory view on ISR.
